The frequency of an am radio is 1.4 x 106 hertz (cycles per second). approximately, how many cycles are completed in a minute?

There are 8,904 cycles per minute. This would be determining the amount of cycles per second, which is 148.4. After you know the amount per second, you can then multiply it by the time, which in this case is 60 seconds, or 1 minute. 148.4 cycles per second multiplied by 60 seconds is 8,904 cycles.
